At just 24 years old, Lily Collins is fast becoming a force to be reckoned with on the red carpet.

Having already made one glamorous appearance at a photo call for her new movie, The Mortal Instruments: City Of Bones, in Madrid, Spain on Thursday, the star followed it up with another fashion-forward number.

Embracing her Spanish surroundings, the actress donned a striking Flamenco-inspired two-piece ensemble for that evening's premiere.

The lady is a vamp! Lily Collins makes an eye-catching appearance as she walks the red carpet at the premiere of The Mortal Instruments in Madrid, Spain on Thursday

Full effect: The 24-year-old embraced her Spanish surroundings by donning a Flamenco-inspired red lace skirt with high-low hemline and matching red and sheer cropped top

The high-low hemline of the red lace dress accentuated the pretty brunette's long legs, while the sheer red detailed cropped top worn over a matching red lace bra added some sex appeal.

Her shoulder-length dark locks were slicked back from her face and curled at the ends in a sophisticated, eye-catching style.

Showstopper: Ruby red stilettos and lips pulled the ensemble together, while her dark brown locks were slicked back into a sleek 'do

Obliging star: The brunette beauty spent plenty of time signing autographs for fans who turned out in droves to see her

Quirky style: Jamie Campbell Bower looked smart in his light grey suit, though he grunged it up with his favourite black biker boots, sunnnies, pocket chain and a patterned handkerchief which he wore sticking out of his back pocket

Swagger! Robert Sheehan stood out in a bright paisley patterned suit, which he teamed with a white shirt and his signature black flip flops as he strutted down the red carpet

The teen fantasy flick, based on the six-part book series by Cassandra Clare, debuted in cinemas in the US on Wednesday.

Predictions for the first weekend of sales put the movie around the $14 million mark - not a substantial amount for such a big-budget offering.

The film cost $60 million to produce and with the sequel, City Of Ashes, set to begin pre-production as early as next month, investors will be hoping the lacklustre opening doesn't affect the film's overall box office performance.
